Air quality monitoring
To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol ...

Flame Photometer for Determination of Na and K using Emulsions and Microemulsions for Sample Preparation
This technique allows use of aqueous standards for calibration rather than relatively unstable organometallic standards and harmful solvents for the extraction. Microemulsions are thermodynamically stable systems composed of water, oil and surfactant. In some cases, an alcohol is added as a ...

Capabilities of the Adsorbent Tube Injector System (ATIS™)
The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes. The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is ...

HF - Hydrogen Fluoride Gas Monitor for Monitoring in Ambient Air
Hydrogen Fluoride (HF) is a commonly used material in various applications, for example in the Chemical-, Mineral Oil and Fuel-, Metal-, Mining-, Electrotechnical- and Glass Industry. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water. When dissolved in water, it forms hydrofluoric acid and releases toxic and aggressive vapors, which are highly corrosive and capable of corroding even glass. Even in smallest concentrations HF is a significant health risk. Concentrations exceeding ...

Stack Emission Sampling for Emission Dust Sampling Options
The reference EN 13284-1 provide two different way about stack sampling, depending on emission conditions. The first option provide sampling with a standard probe with inserted perpendicularly into the duct filter holder to the emission flow. This option is recommended for emissions not involving humidity and with low temperature. It allows using non-perpendicular filter holders to sampling flow, reminding to consider also as part of the sampling all the collected parts ahead of the ...

Continuous Gas Analyzer for Measurement in Humidity or Corrosive Sample Gases
The main challenge of the measurement with the thermal conductivity detectors in humidity gases is to protect the sensor from burning-out. After passing below the dew point, the gas becomes a condensate and the drops cause the detector to burn ...

Stack Emission Sampling for Hydrochloride Acid Chimney Sampling
Hydrochloride Acid chimney sampling according to norm UNI-EN 1911 DLgs.152-2006. The system concerns a heated sonde including a set of glass tools to sample hydrochloride acid sampling gas getting in touch without affecting any metal part. A special impinger’s support deviceis placed outside the sonde, next to the heated recipient holding the filter holder. This process avoid forming condense in the sampling chain with the loss of the specimen. Normative allows two different kinds of sampling, the first one ...
